The core drilling rig is based on an ordinary drilling rig with additional drilling rig shifting chute and hydraulic chuck, which can speed up the drilling tool change, improve the working efficiency and reduce the labour intensity. The core drilling rig is a high-speed drilling rig, suitable for drilling projects such as census exploration, geophysical exploration, road and building exploration and blast hole drilling. Alloy, media, coal, sintered diamond and composite chip bits can be selected according to the different substrates. It can drill sandy clay and rock layers of class 2 to 9.

The core drilling machine adopts a hydraulic automatic feeding mechanism to improve drilling efficiency and reduce workers' labour intensity. Fitted with cage, it forms a double-sided supporting star wheel structure, which can withstand strong impact. The four sets of bearings in the vertical shaft box of the core drilling rig are fixed to ensure that the rotary body has sufficient rigidity to cope with complex geological conditions such as gravel and pebble layers. The core drilling rig adopts a conical clutch, which has outstanding features such as high transmission torque, easy operation and maintenance-free.

Core drilling rigs are a type of portable core sampling equipment that cannot be ignored in maintenance. They are also a factor in increasing the service life of the rig, reducing the incidence of various breakdowns and lowering maintenance costs. The following is an introduction to how to maintain a core drilling rig.

1. Normal load

Ensure that the load used on the core drilling rig is within the permissible range. Generally speaking, the wear of parts is directly proportional to the working load. The higher the load, the greater the degree of wear.

2. Normal temperature

Ensure that the operating temperature of the core drilling rig is within the normal range. Long-term high temperature operation tends to accelerate the wear and tear of parts.

3. Avoiding impurities

Core drilling rigs are equipment used to drill strata. In the sampling process, it is inevitable that there will be some splashing sand and some self-generated metal chips and wear products. This is the time to avoid these impurities from entering the equipment, otherwise it will accelerate the wear and tear of the parts, so it needs to be cleaned and cleansed every day.

4、Avoid corrosion

Core drilling rigs are metal products that will inevitably react with the surrounding media and cause corrosion corrosion. Although corrosion and erosion are inevitable, measures such as cleaning can be taken to reduce the impact of corrosion on the machine.
